Update generator.yaml to esphome 2024.6.0 syntax

[gmn42]

ESPHome has changed the config format for OTA updates and one-wire Dallas temp sensors in version 2024.6.0. It will not accept the old format, so these changes need to be made before the yaml will compile and firmware can be installed. See:

https://esphome.io/changelog/2024.6.0#ota-platforms https://esphome.io/changelog/2024.6.0#wire

Note that I have not personally tested this specific yaml file, but I have made the same changes to mine and they work correctly.
